After looking at the difference and the cost I think I will stay with the stock tail lights on my 2016 Tri Glide. I added little blinker light to the bottom of the trunk. I think there is eight lights on each side and they blink when the brakes are applied and stay on as long as u hold the brake. I think I paid twenty dollars for them at cycle gear years ago. Had them on my last three bikes. U can see them for blocks as they are LEDs and at a cars hood level. Sorry for the long post. Wizard
